I have a 18x36 vinyl liner inground pool suranded by a pressure treated wood deck. The pool and the deck are about 20 years old. Last year we replaced the liner because we could not find where the pool was leaking. When the new pool was installed they put in a hard bottom and a pool base then the liner. The walls were covered in foam. Over the winter we continued to lose water and had to fill the pool every couple of weeks. At one point we stopped filling and waited until the water level went below the light but the was only about a foot and a half left in the shallow end so we refilled again. This summer we lose about a half inch a day.
We we had a technican come over with a leak teac and he found about a dozen pin holes along the bottom wall on one side of the pool. He suspects termites. I am having an exterminator come tomorrow and will try to patch the holes. But can termites get through the pool base and foam?
Has anyone had an issue like this? Do I need to remove the liner to treat?
